Tool/software:

Hello Team, 

IN RVC, we have to crop the image  from this "VCapture -cv=1 -format=uyvy -dmode=none -cpos=6,4 -csize=1280x800 -bsize=1280x800 -spos=0,0 -ssize=1280x800 -pos=0,0 -size=400x240 -fps=1000 -pipeline=4 -nbufs=4 -vsync-pol=1 -hsync-pol=1 -clock-pol=1 -sync-type=4 -discrete-mode=1"  : this is 25%zoom or crop


to this "VCapture -cv=1 -format=uyvy -dmode=none -cpos=199,245 -csize=892x558 -bsize=892x558 -spos=0,0 -ssize=892x558 -pos=0,0 -size=400x240 -fps=1000 -pipeline=4 -nbufs=4 -vsync-pol=1 -hsync-pol=1 -clock-pol=1 -sync-type=4 -discrete-mode=1" and this is 30% zoom or crop

issue is like after this new configuration from the Application team in the resolution and crop setting, causing the color distortion. 

where cyan color got overlayed and there is color distortion, Red become blue, yellow become light green and green become dark green kind?

we are using this serializer, DS90UB914A-Q1, wrt to the zoom or crop operation done on the application side, why distortion has appeared. these are the config for serializer.

This has become a critical issue.  Please do the needful. Is there any reconfiguration required in serializer side?

    Hi,

    Thanks for your message here. I see that the deserializer used is UB914A - could you please confirm which serializer is used? Likely this is UB913A or a similar part - if this is the case can you confirm the operating mode (10 bit or 12 bit mode)?

    For the two video resolutions used, could you please let me know what the horizontal resolution, vertical resolution, data type, and FPS is? From the commands noted above I see FPS marked as 1000, and a number of different resolutions are noted. Please let me know what is output from the sensor to the serializer.

    Best,

    Thomas

    Hello Thomas, we checked, issue is not with the Serializer, and also serializer is in camera itself and issue with Vcapture parameter of the QNX BSP. It resolved now.
